Sidewinder Ti Sprockets

Has anyone used the Sidewinder titanium sprockets and chains? Did you notice any difference? How well to they wear?

Never used them, WAY TO EXPENSIVE.

Look into getting an Ironman... distributed by MSR now. www.msrhp.com

They almost seem worth it especially since they are guaranteed for life. I was also wondering about weight as my bike is starting to get heavy with the flywheel weight and skid plate. How much of a weight difference is there between standard steel sprockets? and how much of a power increase will I see with less rotating mass?

and how much of a power increase will I see with less rotating mass?
None. Rotating mass has no effect on power output. It can effect acceleration, but the weight delta is so small, and so close to the wheel center the effect would not even be measurable, much less detectable.

In an extreme comparison, as between steel and aluminum sprockets, the effect on handling from unsprung weight might be a factor, but that would be it.

What do you mean by so close to the wheel center?

What do you mean by so close to the wheel center?

The inertia mass of a rotating object depends on the placement of the mass relative to the diameter. If you had two identical wheels, one with no tire and a ten pound sprocket, and the other with a 1 pound sprocket and a 7 pound tire, the lighter one with more mass near the outer edge will have far more rotating inertia, and more effect on acceleration, and braking, and also a greater gyroscopic effect.

ok, thanks now that I think of it its kinda common sense.
